From 99ee67351bedf23fe6b969dd94cc2847b397cd20 Mon Sep 17 00:00:00 2001 From: LABBE Corentin Date: Fri, 13 Nov 2015 13:31:51 +0100 Subject: [PATCH] ipmi: constify some struct and char arrays Lots of char arrays could be set as const since they contain only literal char arrays. We could in the same time make const some struct members who are pointer to those const char arrays.
